Yagnam pulverizer supplies jaw crusher. To give maximum strength and minimise vibration, the main frame [body] is fabricated from high class quality ultrasonically tested steel plates [is 2062]; and ribs are provided along the line of stress. Following are some of the constructional features of this jaw crusher : the eccentric shaft is made of en series carbon steel, which is finished to a high degree of accuracy to give an exact stroke to the swing jaw; the raw material is ultrasonically tested and then hardened to ensure a long life.
